:Be'itknownfthat we, HARRISON Woon- MANsE and JOHN AUE, vcitizens of thev United States of America, -residin g Vat :Freeport, finlthe county of Stephenson and AStatez of Illinois, have invented certain vnew and useful Improvements Lin -Pump Valves of which -the following is avspeciiication. Ourl invention relatesto improvements Einf pump-valves, Aits obj eet -being to i provide'` a pump-cylinder with `a valve normally station-1 ary at the lower en d 1 of theA cylinder --andfsos moved therefrom through the 4upper .end off the cylinder. .Thevalve` ispreferably locked inl plaeewhelrin use,lt he. locking device loeingl sov constructed -as-to 'bereadily operated fromrabove,eitherfinjastening the valve ini proper relation toits seat`V or in releasing it to?V permit its removal.

Y

inthe-views, Afis a-.portion of a-tubular pump-cylinder of any desiredI length, the entirecylin'der being made up of any desired number of suitablyfoon-nected -pipesections,lf

per'end ofthe cylinder beingprovided-with?v a suitable discharge -spout A?fFigQ. VThe lower portion ofthe cylin'der or that' in which the plunger works iis preferably provided v with a cylindrical lining' 1A', ofbrassgfastened in place in any desired manner. The lower yendofthe cylinder A isv screwed orotherwise fastened in: the cylindrical: neck B of ,a casting-'formed withzan. annular horizontal shoulder,B/'immediatelyyvithin the Alower end of the cylinder A,'this shoulder being thevalve- Vseat'fof the pump.

From the valve-seat an integrally-formed neck extends downward a suitable distance and is provided atitsilower end with a horizontalv annular ange-BB, adapted to` bel bolted toythe siinilarlyf-iianged upper end of a downwardlyrextendingtube reaching into the waterbelow. 'ln'the upper end of -theneck is .an annular viangefformed at its upper edge with a beveled shoulder-t', and at its lower edge with an abrupt shoulder h?, whose functions areI hereinafter explained. `:The neck B is preferably providedwithlugs b h, by means of whichit maybe rotatedlin ksecuring it on ;the;l ower end of the cylinder.

Qn the valve-seat lB rests :a flexible disk D, preferably of leather -or,rubber, firmly clamped between A twovr diametrical bars C- C above and below'it, respectively, the halves of the upperfface ofthe disk on opposite sides of the bar G beingprovidedwith metal weights d d, adapted to press the disk downward and insure'its contact withthe valve-seat. The upper lbarJC .is of a length .approximately equal tothe; inner diameter4 of the-brass lining A', andthe-lower barg'Cis of such length and its ends are so beveled that the latter conformto the'lbeveled shoulderb atthe upper edge of the annular flange B2, already described. Thevalve comprising the bars()Y C', flexible disk-D, `and weights d d may thus evidently be inserted 'in the cylinder from above, and the bar` C will; insure the proper centering. and seating of the valve.

i To the barfC' are pivoted gtwo dependent armsfE- E,f ree to Qscillat'e` in a vertical plane, and sprovided at their flower. ends with outwardly-extending hooks fel-c, AYadapted `itflen vpressed outward 4to pass'under and engage the shoulder b2 at thezloweredge ofthe an-` nular flangeBz. The outer ends of two arms IOO E E' are pivoted to the lower ends of the arms E E, the inner ends of the two arms E' E being pivoted to each other and also to the lower end of a vertically-sliding rod F, extending upward through the valve C C D, and provided with a stationary collar f lying above the valve and at a suitable distance from the lower end of the rod. The vertical movement of the rod F with relation to the valve C C' D is evidently limited by the collar fand the .inner ends of the arms E E', and the collar `is so placed that when the rod is at its lowest limit of movement (the collar being in contact with the upper face of the bar C) the lower end of the rod and the inner ends of the arms E E are slightly below the outer ends of said arms. The arms E' E thus form a toggle-lever adapted to pass above and below a center midway between the points of connection of the arms E E with the arms E F, and the length of the arms E E is such that when they are approximately horizontal or in the position shown in Fig. 2 the hooks c c of the arms E E lie beneath and in en gagement with the shoulder b2 of the flange B2. Spi-in S S, fastened tothe outer faces of the arms E E above the hooks e e, pressed against the inner face of `the Hange B2, take up the slight loss of motion caused by the arms E E crossing the center and prevent any rattling or looseness of the parts. It is evident that if the rod F be moved upward with sufficient force to carry the inner ends of the arms E' E across the center and into the relative positions shown in Fig. l, the lower ends of the arms E E will be drawn inward and the hooks c e disengaged from the shoulder b2 b2, thus permitting the upward movement of the valve C C/ D.

The rod F, which extends upward from the valve C U' D a considerable distance, is provided at its upper end with a nut j" and lies within a tubular pump-rod made up of two parts connected by a suitable union g, the upper portion being a pipe G of suitable length and of an internal diameter greater than the diameter of the nut, and the lower portion being a tube G', fitting closely upon the rod F, as clearly indicated in Figs. 2 and' (i. The lower portion G of the pump-rod carries a valve-plunger which may be of any desired construction, but is preferably made up of the parts shown in Figs. 2 and (i, in which R R are two rings formed with diamctrical webs r r', respectively. D is a flexible disk resting upon the upper ring and provided with weights d d, and His a diametricalbar restiu g on the disk D directly above the webs r yr. The lower portion of the tube G passes through the bar 1I and webs fr 0', and the parts are held together by means of nuts N N. A suitable packing-ring P encircles the upper ring R, itslower edge being clamped between the two rings R R. The length of the rod F and the distance between the collar f and nut f are such that when the colla-1l is in its norlnal position, as shown in Fig. 2, the

tube G' may move freely up and down within the limits of the stroke of the plunger without striking the nut j. This being the case it is evident that when the lower valve is locked in place, as shown in Fig. 2, the operation of the pump differs in no respect whatever from that of any other, the lower valve and the rod F projecting upward from it being not afffceted in any way by the normal movement of the plunger. If, however, it be desired to remove the lower valve at any time, the upper end of the pump-rod may be disengaged from the usual. operating mechanism, and the pump-rod may then belifted up until the upper end of the tube G strikes and lifts the nut j", thereby lifting the inner ends of the arms E E and carrying them across their cen,- ter and into the relative positions shown in, Fig. l,when the valve will be unlocked. from 4its seat and may be lifted with the plunger entirely out of the cylinder. The insertion of the valve is simply the reversal of the operation just described.

The parts being connected, as shown in Fig. l, and the lower valve bein g suspended by means of the rod F and nut j", the parts are all inserted in the upper end of the cylinder and dropped downward until the lower valve seats itself upon the flange l5' of the casting B, the valve being centered accurately by means of the bar C', as already described. The plunger is then dropped down upon the collar f, which is thereby forced downward, pressing the toggle-lever into the position shown in Fig. 2 and locking the stationary valve in place.

It is evident that the device thus described provides a simple and practical means for the insertion and removal from above of the nornially-stationary lower valve of a pump, and that a valve thus constructed may at any time be removed in a moment for repair or replacement and can be inserted with equal facility. This simple operation obviates the necessity for the removal of the entire pump-cylinder when the replacement or renewal of the valve becomes necessary, and this is a great convenience in every ease and a very great saving of time and labor when the pump-cylinders are of considerable diameter, as is frequently the case. In many situations, and particularly in the pumping of water from shallow wells in the arid regions of the West, pumps of large diameter are coming into extensive use,and in these pumps, particularly, our invention i s of the utmost importance.

The form shown in the drawings has been described with great particularity, lin order to make its construction and operation perfectly clear; but we have no intention of limitin g our invention to the details thus shown and described or to the particular locking mechanism by means of which the invention, as illus trated, is made practical. XVe believe it to be broadly new to provide a pump-eylinder with a normally-stationary valve adapted to be inserted and removed through the upper end of TOO IXO

the cylinder, whether the valve be locked in place or held in place by its own weight or by any other means whatever, and 'we intend therefore to include within our invention a valve susceptible of such insertion and removal, as well as any means whatever for locking the valve, these means being adapted to purpose of thereof and means connectedwith said locking mechanism and extending upward through the valve, whereby saidlocking mechanism may be operated from above the valve and the valve thereby locked in place or released.

2. The combination with the cylinder, A,v

having the valve seat, B, at its lower end and a shoulder, b2, below the valve seat, of the valve resting upon the valve seat and provided with the pivoted arms, E, E, formed with hooks, e, e, adapted to engage the shoulder, the toggle arms E', E, connecting the ends ofthe arms, E, E, and the rod, F, connected with the inner ends of the arms, E', E', and extending upward through the valve, the vertical movement of said rod in one direction being adapted to throw the hooks, e, e, into engagement with the shoulder and the movement of the rod in the opposite direction being adapted to disengage the hooks from the shoulder; substantially as shown and described.

3. The combination with the cylinder, A, having the valve seat, B', and the shoulder, b2, below the valve seat and the valve constructed substantially as .described and comprising the flexible disk, D, resting on the valve seat, the diametrical bars, C, C', lying above and below the disk, respectively, clamping it between th em and the weights, d, d, attached to the disk, of the arms, E, E, pivoted to the bar, O', and formed with hooks,

e, e, adapted to engage the shoulder, the vertical rod, F, passing through the valve and means connecting the lower end ofthe rod with the arms, E, E, whereby the vertical movement of the rod in either direction will throw the hooks, e, e, into or out of engagement with the shoulder, b2.

4L. The combination with a pump cylinder and its valve seat, of a valve resting normally upon the valve seat, and adapted to be inserted in and removed from the cylinder through the upper end thereof, a tubular pump rod lying within the cylinder, a plunger mounted upon the pump rod and having a normally limited movement in the cylinder, locking mechanism attached to the valve and adapted to fasten it in place upon the valve seat or release it therefrom and a rod connected with said locking mechanism and extending upward through the valve and into the tubular pump rod, said rod being provided with stops above and below the plunger, respectively, and separated by a distance greater than the normal movement of the plunger, the downward pressure of the plun ger upon the lower of said stops being adapted to lock the valve in place and the upward movement of the plunger against the upper of said stops being adapted to release the valve and adapt it to be lifted from the cylinder.

5. The combination with the cylinder and its valve seat, of the valve resting upon the valve seat and provided with locking mechanism substantially as described, the tubular pump rod, G, G, and the plunger mounted thereon and the rod, F, connected with the locking mechanism of the valve and extending upward through the part, G', of the pump rod, the rod, F, being provided with the stops, f', f, above and below the plunger, respectively, the downward pressure of the plunger upon the stop, f, being adapted to lock the valve in place and the upward pressure of the plunger upon the stop, f', being adapted to release the valve and to lift it by means of the rod, F.
